DS1 (11) is older than your son so this might not be so relevant, but he was finally diagnosed with ASD last week after 7 years of meetings, reports, form-filling and frustration (we did move counties 4 years ago though, to be fair, and had to start again from scratch)… and I feel like shouting it from the bloody rooftops!
Or at least informing all those people (MIL and an old class teacher, to name but two) who dismissed our concerns and said we should stop looking for problems where they didn't exist. That there was nothing wrong with him. That they didn't agree with 'labelling' children. That he was a loner, a daydreamer, a 'bit odd', rude or 'just a 7/8/9/10-year-old boy'. That he would 'grow out of it'.
We're not broadcasting it but we're not hiding it either - we have told the people who care, those who have some idea of the journey we've been on. And I will have no qualms about telling others as and when appropriate. I don't want it to define him, but at the same time I don't ever want him to feel that it's something to be ashamed of. I feel the same as MrsBobDylan - we're proud of him and it's part of who he is. We've talked through the report with DS1 and he seems happy about it too, as it removes all the uncertainty, which in itself was a source of anxiety. It's official confirmation that it's not his fault that he finds certain things difficult (when he was younger he used to say he 'hated' himself for being 'rubbish'
). It has helped his two younger NT siblings to understand too. And we feel 'armed' for the challenges he'll face during the transition to secondary school. Once there, it will be up to him who he tells amongst his friends. We'll get him an Autism Alert card that he'll be able to carry, so that he can decide for himself if it's ever relevant to show anyone. I once read on here, years ago, about a diagnosis being like an umbrella that you keep in your bag out of sight: as long as the weather's fine you won't need to use it, but you know you know that you've got it with you in case it starts to rain.
Good luck at your meeting. The most positive things I took away from ours (apart from the diagnosis itself) were: information about all the support that we can now access and a comment from the clinician about how 'the world needs more people who see things differently'. I could have hugged her for that!
PS sorry for long post, emotions on the subject still running pretty high!
